help and advice first theater room. Framing done

I have been reading these forums over the years and learning all I can with respect to projectors/speakers/receivers. I was hoping to get some advice as I just finished framing my theater room and I am about to run all wires. I have attached a picture with the layoutThe green box is the subwoofer. The big red box is where my floor is rasied 6 inches for the second row.

I need to know the best possible location for the sub and surround speakers. this setup is 100% movies and I like it very loud with lots of bass. I liked the bass my old velodyne dsp10 put out. Also I wouldn't mind some suggestions on speakers and projector. I care more about 2d picture quality. I like the picture very bright and vibrant.

Front Speakers: Klipsch RF82
Center Channel: Klipsch RC64
Subwoofer: ??? need Help here
Surrounds: Klipsch RS62
Receiver: Onkyo NR818

Projector: Panny 8000U mounting 15 feet from 120" pure white screen.

I am open to two subs if possible. Also should those surround speakers be mounted directly in the corner because if they are the sound will not be pointing at the seating positions due to there style.

My budget for the Projector is 3k
Speaker budget is 3-5k

any help would be great.

I also might go with an epson 5020ub

Tough to find dealers in Canada though.

I have been reading a lot about svs subs.. thanks

The only subs I have ever used was a velodyne dsp10 so aslong as the performance is at par or better I will very happy.
